Guy's been ruining every public duel game he can find on east nl for a long time with blood golem spam and debris, after 10 minutes or so of spam there's huge lag spikes and the game becomes all round glitchy and unplayable. Is there anything that can be done about this from blizzards side?

I didn't find the right solution
